A word from Christine, the 'Minecraft Zombie Pigman' costume creator:

Our daughter, Rachel, loves to play the game Minecraft. Her favorite animals are pigs, and fortunately, pigs are in the game. Since she couldn't go trick-or-treating on all-fours, she decided to dress as a Zombie Pigman from the Nether. The costume is completely made from scratch. The cardboard was found at the hospital I work at. We hand painted it. It was slightly hard to walk in, but she got lots of candy for it!

We cut up some cardboard boxes, marked grids on them, and painted them to look like a zombie pigman. If you notice, some areas are left white with black grid marks. This was due to time cuts and we called her "The Ungenerated Zombie Pigman"
